8. Syncope Epidemiology
Since vasovagal syncope is a subtype of syncope, the epidemiology statistics available are based on syncope. In the United States, it is estimated that it reoccurs in 3% of those affected with 10% having a cardiac cause. Internationally, Japan and Europe has syncope accounting for 1% to 3.5% of visits to the emergency department.
The National Hospital Ambulatory Medical Care Survey found that syncope affects all age groups but most commonly the adult population. There are many studies where patients above the ages of 45, 65, and 80 years old are thought to have a higher risk of syncope.
